DETAILED DESCRIPTION
[0018] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0019] Embodiment: A sandblasting protection fixture for a notebook shell, such as Figure 1 and Figure 2 As shown, it includes a sandblasting machine body 1, a processing chamber 2 is provided in the middle of the sandblasting machine body 1, a sandblasting block 29 is provided above the processing chamber 2, a collecting chamber 30 is provided below the processing chamber 2, and inlet and outlet processing ports 3 are provided on both sides of the processing chamber 2. A conveying assembly 28 is also provided in the sandblasting machine body 1, and the conveying assembly 28 includes a conveyor belt 1 and a conveyor belt 2 arranged in parallel, and the conveying directions of the conveyor belt 1 and the conveyor belt 2 are opposite. The processing personnel enter and exit the processing port 3 from one side to input the notebook shell to be processed, and the conveyor belt 1 conveys and realizes the sandblasting and polishing of the surface in the processing chamber 2. At the same time, the notebook shell is turned over at the other side of the processing port 3 and switched to the conveyor belt 2 for transportation, so as to continue to polish the opposite side of the shell in the processing chamber 2 until the material is finally discharged from the inlet and outlet processing port 3.
[0020] Considering the position-limiting protection of the notebook shell to be processed, a movable carrying tray is movably connected to the conveying assembly to carry the notebook shell in a position-limiting manner. The carrying tray includes a body 4, a convex cavity 5 and a concave cavity 6 arranged on both sides of the body 4, and the convex cavity 5 and the concave cavity 6 are respectively matched with the contours of the opposite sides of the notebook shell surface, which can meet the requirements of sandblasting and grinding of any side of the notebook shell surface. The processing personnel can just engage the notebook shell with the corresponding convex cavity 5 and the concave cavity 6.
[0021] like Figure 2 , Figure 3 and Figure 4As shown, in order to further improve the fit between the notebook shell and the supporting material tray, adsorption grooves 7 are provided at the bottom of the convex cavity 5 and the groove cavity 6, and a negative pressure generating block 8 cooperating with the multiple adsorption grooves 7 is provided in the main body 4. When the processing personnel snap the notebook shell into the convex cavity 5 or the groove cavity 6, the negative pressure generating block 8 can achieve the adsorption effect on the surface of the notebook shell, thereby improving the limiting stability of the notebook shell, improving the reliability during sandblasting and polishing, and reducing the activity and excessive deformation extension of the notebook shell. The notch of the adsorption groove 7 is provided with an elastic protective gasket 23, which can improve the reliability of adsorption tightness while also protecting the shell surface and reducing the occurrence of scratches.
[0022] Since the relative jumping of the material tray still occurs during the conveying process of the conveyor belt 1 and the conveyor belt 2, the two sides of the body 4 are respectively movably connected with the limit block 9, which is convenient for the processing personnel to quickly and efficiently realize the instant limit locking of the material tray and the conveying component. The limit block 9 includes a sliding block 10 that is slidably plugged with the body 4 and a limit block 11 that is movably connected with the sliding block 10. The side of the body 4 is provided with an elastic card slot 15 for the sliding block 10 to be slidably plugged, and the elastic card slot 15 is provided with an elastic telescopic tension spring 16. The sliding block 10 and the elastic card slot 15 are both provided with a pull ring block 17 that cooperates with the elastic telescopic tension spring 16 on the groove wall. The processing personnel can realize the elastic clamping and clamping of the conveyor belt 1 or the conveyor belt 2 through the limit blocks 11 on both sides to ensure the stability of the position state of the material tray relative to the conveying component. Considering that the processing personnel need to flip the body 4 to meet the requirements of the flipping and grinding of the notebook shell, the end of the sliding block 10 is provided with a through groove 12 for the limit block 11 to be engaged. The limit block 11 moves in the through groove 12 under its own gravity. The two side walls of the through groove 12 are provided with sliding support blocks 13. The two sides of the limit block 11 are provided with sliding vertical grooves 14 that slide with the sliding support blocks 13. This ensures that the limit block 11 can slide down synchronously during the flipping of the body 4 by the processing personnel, which is convenient for the processing personnel to engage the limit block 9 with the conveying component. The end of the limit block 11 is also provided with a limit support plate 26, and the limit support plate 26 is provided with a wear-resistant anti-sliding block 27, which helps to further improve the locking stability of the limit block 11 and the conveying component and reduce the occurrence of relative sliding activities during the continuous impact of the sand material.
[0023] like Figure 2 and Figure 3As shown, during the sandblasting and polishing process, the processing personnel will also shield the exterior of the notebook according to the local special protection requirements of the product. The main body 4 is also movably connected with a sandblasting baffle 18 to meet the special process requirements during the processing. Positioning grooves 19 are provided on both sides of the sandblasting baffle 18, and the main body 4 is provided with a positioning plug 20 that cooperates with the positioning groove 19. After completing the fitting of the notebook shell with the convex cavity 5 or the groove cavity 6, the processing personnel will plug the positioning groove 19 on the sandblasting baffle 18 customized according to the actual protection contour into the positioning plug 20 to achieve the shielding of the local contour during the sandblasting process. The main body 4 is provided with an installation groove 21 for the positioning plug 20 to be plugged in. The bottom of the installation groove 21 is provided with a compression spring 22. The positioning plug 20 adopts an elastic clamping structure to meet the elastic compression of the surface of the conveyor belt 1 and the conveyor belt 2 after the load tray is turned over, further increasing the friction contact force and reducing the movement of the load tray relative to the conveying assembly.
[0024] like Figure 1 and Figure 2 As shown, the cavity walls of the protrusion cavity 5 and the groove cavity 6 are also provided with a sand material air guide groove 24, and a fan unit 25 is arranged in the sand material guide groove 24. Under the premise of not affecting the contact effect of the sand material spraying on the surface of the notebook shell, the fan unit 25 realizes intermittent opening and closing of the blowing operation under the control of the preset control instructions, which helps to reduce the accumulation of sand material on the edge and the opening inside the notebook shell during the sandblasting process, realizes the effective blowing away of the deposited sand material during the sandblasting process, and improves the reliability and stability of the sandblasting process.
[0025] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
